Problems solved by technology

[0005] (1) The dosage form is mostly emulsifiable concentrate, which contains a lot of organic solvents, which is easy to cause side effects on crops; a few herbicides are in the form of suspoemulsion, but the stability is poor, the suspension rate is low, and the pouring property is not good;
[0006] (2) Most of the existing herbicides are used for soil spraying after corn seeding and before emergence. This treatment method has an unsatisfactory control effect on weeds in corn fields and is not highly targeted;
[0007] (3) When the existing herbicides are used to control weeds in corn fields, they have certain side effects on corn plants, poor safety, and have a certain reduction effect on yield

Abstract

The invention provides a weed killer containing cordate houttuynia extract. The weed killer comprises the following raw material components in percentages by weight: 4% to 8% of propisochlor, 3% to 7% of cordate houttuynia extract, 2% to 6% of dimethomorph, 4% to 7% of difenoconazole, 3% to 6% of propiconazole, 1% to 4% of Azoxystrobin, 10% to 16% of solvent, 2% to 5% of emulsifying agent, 1% to 4% of diffusion wetting agent, 0.1% to 0.6% of defoamer, 0.2% to 0.7% of anti-sludging agent, 1% to 3% of anti-freezing agent and the balance of water. The invention also provides application of the weed killer in saline-alkali soil corn planting. The weed killer has the beneficial effects that the control effects of common weeds such as field bindweed, amaranthus retroflexus, setaria glauca, Chloris virgata and wheat grass in saline-alkali soil corn fields reach 96.4% to 99.3%, 95.3% to 98.9%, 96.1% to 99.5%, 95.3% to 98.9% and 96.1% to 99.6% respectively 30 days later after application.
